Arnold GPU does not work that way. So not possible.
If you think it's needed, do request, but I don't think it will sit high on the todo list, there are other more relevant issues to tackle first.
Hello Mads,
thank you for the answer. At this moment is for me Arnold GPU only Active Shade Mode renderer, and you can only use Arnold maps and shaders, no legacy shaders or original 3dsmax stuff. The integration of Arnold in 3dsmax still has room for improvement. It looks like mental ray in new clothes. 🙂 But Arnold is very powerful, and a great CPU Renderengine.
